*** Official 8800GTS 512MB (G92) O/C Thread ***

[ArchAngel777]

My 8800GTS Is set to arrive on Friday. Most people probably do not have theirs yet... Be sure to post your overclock and temperature as well. I am curious to see how well the memory overclocks more than I am the core at this point. More importantly are these cards prone to failure over 2000Mhz memory clock? One has to wonder since no MFG is currently selling a card beyond 1952Mhz...

Edit **

Ok, I think we should all be using the same program to test for artifacts. My choice is ATI Tool. If anyone has anything better, please share.

If ATI Tool results in any yellow dots within 1 minute, I could not consider that a pass. So, lets post the best clocks we can get with ATI tool passing 1 minute with zero artifacts. Then you can post the speed that you set it at for most games. I myself don't mind when ATI Tool gives me a few artifacts, because you will never notice them in game. But for testing stable clocks, this is the best method, IMO.

I got my EVGA 8800GTS 512.

Stock: 670/1875/1944
First try OC: 793/1911/2060

I had an 8800GT and it didn't even come close to these. I will keep pushing it and play with the fan settings..

I wonder if the gts has the same inherent defect that johnnyguru talked about in the gt re the 2000mhz memory level?

 

[Cookie Monster]

Review sites are hitting 2.2Ghz on memory. Seems like memory is more OCable then before, or they are using faster memory or it could be because of the better power circuitry of the GTS PCB.. (Not sure about this).

Who wants to be the guinea pig?

 

[error8]

If the card starts having problems at 2000 mhz you can just rma it. Nobody will ever know about your OC.

I saw 670 core on EVGA website, a surprise because resellers are listing it at 650. But shader is clocked to 1875 stock?? Wow. :thumbsup:

found this post @ 800/1950/2200, hope it's for real...

When the card first went up on EVGA's website it was actually listed as having a 650 Core as well and then later changed to 670. Apparently this mistake filtered down to the e-tailer, although upon checking today a lot of sites have updated their Core Spec to 670 Mhz.

I am skeptical on stock of 1875... Typo and he meant 1675? I mean, that would be awesome if it was stock at 1875 and I hope it is... But it seems more likely to be 1675.

The Shader Clock is listed on EVGA's Website as 1674 Mhz. , so it looks like he just made an honest mistake....

Yes, just a typo.. definitely meant 1675 there.

I was able to push the clocks up to 811/1913/2190, but started getting some minor artifacting. Heat is not an issue at all with this card. Running Crysis at these clocks in 1900x1200 at High, the max temps I saw were 64, but it maintained around 62. That is at 70% fan speed. Also, Crysis is definitely playable at those settings. More so than my OC'd 8800GT. Nothing scientific, but the Riva logger was showing 18 and 19's and maybe peaking at 23 or 24 with the GT.. Now the lowest I see is around 22 and I am peaking around 28. It's a small number of FPS to improve, but its a world of difference in playability.

I think the limiting factor here is the shader. Every time I touched that clock, I would artifact.

 

[bleeble]

What are you guys using for stability testing? Just 3dmark/games or something like ATI Tool's artifact scanner?

I ask because at 775 core I get yellow artifacting in ATI Tool that the program doesn't detect. If I let it get bad enough, my computer locks up. I don't see artifacting in any other game or benchmark I've tried though. Any idea why?

So far I have 765/1825/1070 completely stable. I'm working on increasing the shader clocks right now.

I would personally prefer us to be using ATI tool. That saves us from using ambiguous terms. I know that with my 8800GTS (G80) I could set core to 620Mhz and games looked and played fine. ATI Tool reported about 20 artifacts at any given time. Brought my card back down to stock, poof, they are gone. So, while we all may have different standards, ATI tool allows us to set the playing field to factual reporting, IMO.

I will update the OP with this information to help us really see what the cards are really capable of.

Good info, thanks for the time saver. I'm gonna shoot for 775/1800/2050 and leave it there. Fan speed and temps look great. I read fan is audible over 40%, but I have a modded P180 with extra dampening so I think I'll do 50-70% on fan.

Tomorrow...

 

[chizow]

Small request for all those getting their G92 GTS' in the next few days.

If you guys could run a few benchmarks with only a change in memory frequency, maybe 3DMark06 and Crysis' SP demo's built-in bench. Certain someone seems to think G92 is bandwidth limited.

Thanks and enjoy your cards!

How are the noise levels at 70% sil0nt? I found 55% the most tolerable with the GT. And thanks for the Crysis info, I may give the game another shot now.

Tomorrow...

Final stable, everyday OC: 791/1903/2130

70% fan is definitely audible, but in game its not a big deal (volume of game is greater than volume of fan). I also have a P180 with 7 12cm fans running very low RPM, so my system is usually quiet, but cool... so I wouldn't consider running 70% unless it was reasonable.

I setup my RivaTuner profiles to run at slightly underclocked (600/1500/1800) and 30% fan outside of games (61C and quiet) and overclocked (791/1903/2130) and 70% fan in games (63C and manageable noise). I also set some temp thresholds for 50% and 100% fan in case i need some in between or extreme cooling.

Also, I occasionally artifact in ATi tool which I use for stability testing, but rarely do I see problems in games. Once I find my max in ATi tool (one artifact every 3-4 minutes), then I back it off quite a bit and leave it there. From my experience, if I am at a clock where I artifact in ATi tool but not in games, I might have general stability, but the temps run much hotter. Dropping 5% off my max clocks rarely impacts overall performance, but it reduces heat, and in my opinion that improves system stability and longevity.

 

[imported_trajan]

Anyone got any thoughts on how soon factory-OC'd variants will appear? E.g. whats the general time lag? I'm doing the eVGA stepup to the G92 GTS but am actually losing money on this.. so I wouldn't mind getting a slightly pricier OC version. I've only got 16 days to wait, though!

I have one general worry which maybe someone will know more about. It seems to me that if I were a card maker, I'd be testing all my products prior to boxing to see which have great OC potential, and then stashing those aside to market later as factory OCs.. If that were true, it means the stock cards being sold have already kind of been picked through and the best taken out.

70% fan speed on the 8800GTS may very well be quieter than 55% on the 8800GT. At the very least, the pitch itself is probably more tolerable. Who knows at this point, but I will report noise when I get mine too.

 

[bleeble]

With my radiator fans (3x Yate Loon D12SM) at 12V, the GTS is VERY noticeable at 70%. At 50% it's a bit louder than my case/rad fans. At or below 40% I can't hear it at all. 40% drops my idle temps from 56C to 49C, compared to the auto settings. That's with warm air from the radiator (while I'm running Orthos) being sucked into the card.

So any ideas on why I'm seeing yellow artifacting in ATI Tool that it won't detect?

Should be here soon enough. And I'm pretty sure that's what manufacturers have been doing since factory OCed cards were first offered.

 

[sil0nt]

I've had totally random experience in the last 7 or so years I've spent overclocking video cards, and when mfg's started offering factory OC'd cards, nothing changed. Sometimes a stock clocked card will OC very well, and sometimes a factory OC'd card won't. You never really know. I just buy what is available from companies I trust.

Yeah... at the risk of sounding like an eVGA ad, I'm glad I went with them, because this step up thing is saving me from having completely wasted money on the pre-G92 cards. And I understand they have a great guaruntee, which covers me if I do something foolish with overclocking (?).

I'm new to the market though .. in your experience, whats the general turn around time for the factory OCs? Should I wait the two weeks I have left and hope something pops up, or is tihs going to be a month or more before they're around?

If you've already got a card than can play the games you want acceptably, you might as well wait to see if the factory OCed ones come out in the next couple weeks. If you really want/need something now, just go ahead and do the step-up. There's typically not a huge performance difference between a stock and OCed card anyway.

For the OC I posted earlier, I had the fan running at 40%. I'll have to check the load temps after I get home from work. I'll probably be updating with new OCs soon. Once I max this thing out on air, I'll slap my MAZE4 and some RAMsinks on there and see if it makes a difference.

EDIT: I grabbed an eVGA too BTW. With a new generation of cards supposed to be out in Feb, hopefully I'll be able to step-up.

 

[ArchAngel777]

FedEx still says that my card departed City of Industry... Usually by this time, it arrived in Minneapolis... I sure hope the estimated delivery holds true!
